To (l/ZZ whom it may concern:

Be it known that I, GUDMUND DAHL, a subject of the King of Sweden,residing at Schat- .tau, in Moravia, Austria-Hungary, have inventedcertain new and useful Improvements in Devices for Use in theManufacture of Ornamented or Figured Plates or Tiles of Cement, Clay, orLike Material, of which the following is a specification.

The device forming the subject of this invention has for its objects thereduction of the cost of and rendering more rapid the production ofornamented or figured plates or tiles of cement, clay, or like material.The necessary amount of color for the pattern or figures is exactlymeasured out and automatically and uniformly distributed in the hollowspaces of stencils or templets used in a known manner for producing thepattern.

The improved device, which is adjustably laid on the press-frame abovethe stencil or templet placed therein, consists for each color of twoplates which inclosea slide and which are provided with openingscorresponding to the hollow spaces in the stencil or templet to befilled. Of these openings those in the plate arranged above the slideform measuringchambers which after they have been filled contain thenecessary amount of color. This color when the slide is drawn out fallsdown irito the hollow spaces in the stencil or temp et.

In the accompanying drawings there is shown a stencil inserted in thepress-frame, with the device serving by way of example for measuring outthe amount of color required for the figure of the pattern.

In the drawings, Figure 1 is a vertical section through the said parts,while Fig. 2 shows the measuring and filling device in plan. Fig. 3 is asectional detail of a modification.

The stencil b, which is inserted into the press-frame a, has its walls 0defining the outlines of the pattern sharpened at the top and bottom andconnected together and stayed against the press-frame by stays anddistancepieces d, which are sharpened at the upper edge. This stencilfor the purpose of being charged or filled with color is covered by themeasuring and charging or filling device, which consists of two plates fand g, held at a short distance from each other at two parallel sides bystrips or liners. Between these plates there is arranged a movable plateor slide it, guided by the said strips or liners. The plate g serves toguide the slide it and to hold the same in place. If the plate g werenot employed, the slide it would be liable to fall down when the upperplatefis removed.

The upper plate f of this measuring and charging or filling device, ofwhich there are as many as there are colors in the pattern of the plateor tile to be made, contains openings 7/ z', corresponding to theopenings or hollow spaces in the stencil to be charged or filled for thetime being. Similarly the lower plate 5 has openings Zr, which afteradjustment of the device on the press-mold (by means of pins m) arebrought into position exactly over the hollow spaces of the stencilwhich are to be charged or filled.

The openings r, c' have a height which corresponds to the height of thelayer of color in an uncompressed condition and contain wiping-bars a,of sheet metal, which are set more or less perpendicular to thedirection of motion of the slide or are inclined relatively to thesurface thereof in order, on the one hand, to prevent the carrying alongof the color by the slide when the latter is drawn out, and, on

the other hand, by reason of the inclined position of the bars to guidethe color toward the corners of the hollow spaces of the stencil. Thedistributing-bars n, Fig. 1, in the hollow spaces of the stencil alsoserve for the latter purpose.

Instead of the above-described wiping-bars in the openings of the upperplate with large one-color surfaces wire sieves a, Fig. 3, are employed,which are stretched over the corresponding interrupted part of thestencil.

The device, with the slide pushed in, is filled with the color for whichthe device is designed. After wiping off the color it is then placed onthe adj usting-pins of the press-frame and the slide drawn out. Thecolor then falls in the prescribed thickness and uniformly distributedinto the corresponding hollow spaces in the stencil.

The process is repeated in the same manner with the second and eachfollowing measuring and filling device in order to fill thecorresponding hollow spaces of the stencil, according to the number ofcolors in the pattern.

Finally the stencil is drawn out of the pressmold, and on the parts ofcolor forming the pattern and distributed in accordance therewith alayer of cement or clay corresponding in thickness to the plate or tileis applied and the whole pressed to form the finished figured plate ortile.

Having thus fully described my invention, what I claim. as new, anddesire to secure by Letters Patent, is

1. A color measuring and charging device for manufacturing plates ortiles comprising a pair of plates for each color, and a removable slideinterposed between the plates, each of said plates provided withcorresponding openings corresponding to the hollow spaces in the stencilto be filled, the openings in the upper plate in connection with theslide forming measuring-chambers for the color.

2. A color measuring and charging device for manufacturing plates ortiles comprising a pair of plates for each color, a removable slideinterposed between the plates, each of said plates provided withcorresponding openings corresponding to the hollow spaces in the stencilto be filled, the openings in the upper plate in connection with theslide forming measuring-chambers for the color, and means arranged inthe openings of the upper plate to prevent the carrying along of thecolor by the slide when the latter is drawn out.

8. A color measuring and charging device for manufacturing plates ortiles, comprising a pair of plates for each color. a removable slideinterposed between the plates, each of said plates provided withcorresponding openings corresponding to the hollow spaces in the stencilto be filled, the openings in the upper plate in connection with theslide forming measuring-chambers for the color, and means arranged inthe openings of the upper plate to prevent the carrying along of thecolor by the slide when the latter is drawn out and for guiding thecolor toward the corners of the hollow spaces of a stencil.

4. A color measuring and charging device for manufacturing plates ortiles comprising a pair of plates for each color, a removable slideinterposed between the plates, each of said plates provided withcorresponding openings corresponding to the hollow spaces in the stencilto be filled, the openings in the upper plate in connection with theslide forming measuring-chambers for the color, and wipingbars arrangedin the openings in the upper plate for the purpose specified.

5. A color measuring and charging device for manufacturing plates ortiles comprising a pair of plates for each color, and a removable slideinterposed between the plates, each of said plates provided withcorresponding openings corresponding to the hollow spaces in the stencilto be filled, the openings in the upper plate in connection with theslide forming measuring-chambers for the color, combined with thestencil, distributing-bars in the hollow spaces of the stencil, andwiping-bars in the openings in the upper plate.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

GUDMUND DAHL.
